INSOLE-TEMPERING DEVICE.

To all whom it may concern.

Be it known that I, NORMAN J. NICHOL- SON, a citizen of the UnitedStates, residing at Revere, in the county of Sufiolk and State ofMassachusetts, have invented an Improvement in Insole-Tempering Devices,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the draw ings representinglike parts.

The invention to be hereinafter described relates to devices fortempering insoles and more particularly to such devices for thustreating the channel of insoles prior to securing the upper, welt, andinsole together.

As well known by those skilled in the art it is usual to wet or temperthe channel of insoles in order to facilitate the passage of thefastening means by which the upper,

welt, and insole are secured together. This is preferably done after theinsole and upper have been assembled on the last in order that whensubjected to the action of the Welter the parts shall be in propertempered condition. One means heretofore employed has been a squirt canor brush or like device in the hands of an operative, but this has beenobjectionable not only because the channel would not be uniformlysupplied with the tempering liquid, but through haste or carelessnessthe upper would often be wet and consequently injured. Attempts havealso been made to equip the Welter with a channel moistening device, butthis causes objectionable crowding of mechanism at the stitching pointand where the moistening device is controlled in its action by themachine, as has been the case, the tempering liquid has not respondedwith suflicient promptness, so that at the commencement of the sewingoperation the channel would not be tempered; moreover, when thussupplied the tempering liquid has not sufficient time to act upon ortemper the leather before the needle seeks to penetrate.

With these general considerations in mind, the aims and purposes of thepresent invention are to provide a hand operated device for tempering ormoistening the channel of insoles, which shall be simple inSpecification of Letters Patent.

construction, efiective in operation, and whereby the channel will beuniformly tempered without danger of wetting the upper of the shoe, allas will hereinafter appear from the description and accompanyingdrawings of one form of the invention, which in its true scope isdefined by the claims.

In the drawings: Figure l is a diagrammatic view showing the manner ofhand manipulation of the invention in moistening the channels of shoesoles; Fig. 2 is a central transverse section of the end portion of themoistening device, taken on the line 22, Fig. 3. Fig. 3 is a section onthe line 33, Fig. 2; Fig. 4 is a section through the hand portion of theinstrument on the line M, Fig. 1; and Fig. 5 is a side view of themoistening device detached.

As indicated in part by Fig. 1, a suitable tank 1 may be provided forholding the desired tempering liquid, which may be water, if preferred.Connected to the tank is a flexible hose 2 by which the liquid thereinmay be directed to the moistening device through the tubular metal stem3. The moistening device preferably consists of a metal tubular piece 3having a downturned end 4 to which is connected the nozzle 5. It isdesirable that the nozzle 5 be detachable from the moistening device 3for purposes of cleaning and repair, and as one form of means to thisend, it is preferably connected thereto by suitable screw threads 6.

Below the screw threaded connection between the end 4 of the moisteningdevice and the nozzle 5, the latter is provided with a chamber 7 whichterminates at its lower end in a smaller opening or passageway 8 throughwhich passes the stem 9 of a closure valve, the head 10 of which isadapted to be seated on the shoulder 11 at the lower portion of thechamber 7 to close the passageway 8 to the passage of moisture throughthe moistening device. From the construction thus far described it willbe apparent that if the stem 9 of the valve in the lower end of thenozzle, which normally projects below the end of the nozzle as indicatedin Fig. 5, be pushed inward, the head 10 of the valve will be unseatedor raised from the shoulder 11 of the nozzle whereupon liquid is free topass through the nozzle and the passageway 8 as will be obvious.Ordinarily the pressure of liquid which fills the moistening device 3and bears upon the head 10 of the valve, will be sufficient to keep thevalve seated to prevent passage of liquid through the nozzle; but as anadditional means to this end a spring 12 may, if desired, be interposedbetween the head 10 ofthe valve and the shoulder 13 formed by the end ofthe portion 4 of the moistening device. The lower end 14, Fig. 2, of thenozzle 5 is preferably reduced in size and made circular, as indicatedin Fig. 3 and on this circular portion of the nozzle is mounted the plow15 which is free to rotate on the end of the nozzle as clearly indicatedin Fig. 5. As one practical means of connectingthe plow 15 to the end ofthe nozzle 5 the present invention contemplates the circu'lar recess 16formed on the lower end of the nozzle which is adapted to be engaged bythe end portion of a screw plug 17, the construction being such thatwhile the part 17 maintains the plow 15 on the end of the nozzle, itdoes not obstruct free rotati've movement of the plow on the end of thenozzle.

'As well known by those skilled in the art the insoles S have a channellip 18 formed thereon, and said lip is upturned prior to the action ofthe welter. It is liable to be down-turned into the channel by coming incontact with exterior objects and in order that it may be properlyupturned by the end of the nozzle as the latter is moved along thechannel of an insole, the plow 15 is provided, and is preferably of theshape indicated by Fig. 3, so that as the nozzle end is moved in thechannel of the insole toward the toe portion thereof, the plow 15 willproperly guide the end of the nozzle and, should the channel lip bedownturned at any point the plow 15 will serve to raise the channel lipand prevent the end of the nozzle from escaping from the channel. As theend of the nozzle moves about the insole channel and approaches theportions of the channel where the contour of the insole changes, as atthe toe, the plow 15 will readily swivel around the end of the nozzleand accurately guide the nozzle in its movement about the toe portionand other parts of the channel.

The insoles and uppers assembled on the lasts are supported in anydesired form of rack with the soles S uppermost as indicated in Fig. 1,wherein a convenient form of rack 19 is indicated in part, thesupporting portions 20 of which may be preferably so formed that theywill support the assembled p'arts without danger of the shoe moving'endwise or becoming disengaged in the through the flexible connection 2into the moistening device 3, and inasmuch as the moistening device hasthe downturned end portion 4: carrying the nozzle, it is desirable thatthe handle be formed non-circular in cross section as indicated "in Fig.4, whereby the operative by grasping the handle firmly may prevent themoistening device 3 from falling over laterally one way or the. otherwhile he pushes it around the channel of the insole as indicated in Fig.1.

From the construction described as one practical form of the invention,it will be apparent that the channel of insoles maybe properly temperedor moistened without the necessity of the operative taking the shoesfrom the rack.

In operation the operative grasps the handle 21, as indicated by dottedlines in Fig. 1, and inserts the nozzle portion of the moistening devicein the channel along the heel portion of the insole. The weight of themoistening device itself is usually suflicient to push the stem 9 of thevalve upward in the nozzle and to unseat the head 10 of the valve inorder that liquid may pass through the. end of the nozzle from thechannel. He may, however, give sufficient pressure to the moisteningdevice to force the stem 9 upward in the nozzle and unseat the head 10of the valve and thereafter push the moistening device along the channelof the insole around the toe and back again, as indicated in Fig. 1,during which time liquid will freely pass through the end of the nozzleand the channel of the insole be uniformly and properlv tempered. As theoperative removes the moistening device from contact with the insole thepressure of the liquid on the head 10 of the valve will force the valvedownward and seat the head on the shoulder. 11 of the nozzle, with thenozzle, will guide the end of the nozzle along the channel of the insolethrough the channel moistening operation.

From the construction described it will be further noted that the flowof the tempering liquid through the nozzle is at once checked as soon asthe end of the stem 9 is lifted from the channel of the insole, wherebythe upper of the shoe and those adjacent thereto in the rack 19 areprotected and injury thereto avoided.

Obviously, the form of the nozzle, either with or without the plow 15,and the precise form of the plow may be varied in the true scope of theinvention as definitely pointed out by the claims.
